Our goal is to save sensitive data in a MySQL database in a responsible way, and be able to read/write it programmatically in a PHP web application. Asymmetric encryption would be best, but is not practical here. Symmetric encryption with a strong algorithm and hard-to-guess cipher is acceptable, but not if we store the cipher in plain text on the same server where the database credentials also live in plain text!

This work-in-progress is subject to change if/when I come up with a better scheme, but for now, the plan is to:

• store the cipher as a vault secret;
• configure TLS authentication so that our PHP application can log in, and then
• create a token that allows its bearer to read the secret (our cipher);
• use a PHP component and our cipher to encrypt/decrypt our sensitive data.

Floating serenely through a peaceful abyss, a sigh escapes; content.
A siren wails, you're jolted from your respite
/dev/xsdb1 is at 100%

A cacophony of alerts screech from the phone.
Upset is the fragile balance, failure cascades.
Was only a matter of time.
Get some coffee.

All you ping seems to crumble, machine after machine fall; a massacre of uptime.
